X/Y 90 Degrees



用兩隻心型指向性的麥克風成90度，這種錄法定位焦點最好
也適合在困難的環境中使用
缺點低頻不多

In this method, we take two cardioid microphones and place the capsules at a 90 degree angle to each other. In this technique, the microphone on the left is actually wired to the right channel, and vice versa, because of where they're pointing. This technique is considered by many to be the perfect way to get started in recording stereo.

With this technique, you'll get get a recording that's very focused, with a tight low-end response. You'll lose a little depth, but that's made up for in the lack of ambient information. This technique is best used if you're in a difficult-sounding room, and need to "zoom in" on the sound as best as possible.

When used with figure-8 (bidirectional) microphones, XY is called the Blumlein Technique.
